This is a spin-off of a webcompat issue https://webcompat.com/issues/6603

Firefox will not break after the hyphen-minus while Chrome and Safari do.

[Original bug title was misleading: the example shown has the hyphen-minus between two digits, not "immediately followed by a letter".]

Currently, Gecko deliberately does not break in a sequence <digit, hyphen-minus, digit>:

Changing this could have pretty widespread implications; it's not immediately clear to me whether on balance it would be an improvement or not.

Jonathan, yup. 
Reporting for recording the difference, not necessary to create a change in the meantime, and given this is one site only I don't think it is a priority. 
Thanks for fixing the title.

The layouts of the websites hitting this issue have changed, and no longer seem to have the issue. Let's drop the webcompat flag for now.
